1.) Always True: (i.e.) 2,4,5,8,10,12 If you took the numbers or "points" 4 and 10, then you should deteremine the geometric sequence and the multiplier.

2.) Never True: (i.e.) An individual can't just change one number if he or she plans to change a parabola becuase two points must be of equal measures in order for the line to curve.

3.) True: (i.e.) Special right triangles can be calculated easier than other regular triangles.

4.) Always True: (i.e.) If you are giving an algebraic formula for an arithmetic sequence, then one should be able to figure it out because usually with equations you have to figure out the formula. 1 + 2 + 3 + 4 + 5 + 6 + 7/ (Given formula- 1(x) +1 = x)

5.) Always True: (i.e.) The domain is the x plane of the graph and 0 is an important number because it is the first number that starts a sequence. When ever someone begins to count they would most of the time start with 0, then count on to the next 10 set of numbers.

6.) Sometimes True: (i.e.) Not all the time can a graph give you all information to start an algabriac formula. The graph could have points but it does'nt mean that one can get all information just based off two points you need a more from the graph if it doesn't already supply it.

7.) Always True: (i.e) Any value of an exponent can be positive or negative because if when you are solving for the answer, sometimes there are negative and positive values.

8.) Sometimes True: (i.e) Often arithmatic sequences are whole numbers, but sometimes fractions are in these sequences as well. 1/2, 1/3, 1/4, 1/5 etc.

9.) True: ???

10.) Sometimes True: ???

11.) Sometimes True: ???

12.) Always True: (i.e.) Any time you are given a formula for an equation, you should be able to determine he initial value because all information and data has been given.

13.) Sometimes True (i.e)Sometimes it is poosible the that result of an equation could be positive but then agian negative which is why it is sometimes true for the value of an exponent to be positive.

14.) False: (i.e.) Multiplicat is not the only way to determine if fractions are equal because there are other ways such as division, subtraction and addition.
